Dynamite Blue finally has a global launch date. Kosmo's12 has announced that its story-driven 2.5D turn-based collection RPG will launch worldwide on September 30, 2026 across the App Store, Google Play, Steam and STOVE, following an earlier Korean release through ONE store.
The project comes from a newly formed studio that reunites several core members of the team behind Exos Heroes. Rather than returning to high fantasy, Dynamite Blue moves into the lighter cyberpunk setting of Vierhaven, combining pixel-art battles, more than 60 characters, personal stories and turn-based combat built around six-element matchups and Guardian Stone Breaks.

Trailer, Steam, Google Play and the World of Dynamite Blue
The Global Launch Covers Four Storefronts
The latest announcement establishes September 30, 2026 as the worldwide launch date, naming four distribution platforms directly: the App Store, Google Play, Steam and STOVE.
Apple's listing already displays the date as the expected release. Steam, however, was still showing Coming soon when verified, meaning Valve's public store field has yet to reflect the newer announcement.
Pre-registration is open on mobile, while PC players can add the game to their Steam wishlist.
Korea is already ahead of the global rollout. A domestic version has been available through ONE store since July 1, and Kosmo's12 says the worldwide build incorporates live-operation experience and player feedback gathered from that release.
Vierhaven Divides Its Cyberpunk City Into Three Layers
The story takes place in Vierhaven, a futuristic megacity shaped by increasingly close integration between people and machines.
A technology called Jagear allows human body parts to be replaced with machinery, becoming widespread enough to influence the city's society and infrastructure.
Vierhaven is split into three layers.
Air Ground sits above the rest and serves the privileged. Mid Ground houses ordinary citizens, while Under Ground lies below, described as a far more lawless place where little light reaches.
The small Dynamite Blue agency operates from Mid Ground.
Its crew has little money and few connections, taking whatever work reaches the office. Seemingly minor jobs gradually pull them into incidents with consequences stretching across the city.
More Than 60 Heroes Receive Their Own Pocket Stories
Characters are one of the game's central pillars.
Kosmo's12 says Dynamite Blue contains more than 60 heroes, with each designed to function as more than a combat unit.
Every hero receives a Pocket Story, a personal narrative exploring their background, relationships and place within Vierhaven beyond the main plot.
The approach draws on the development team's experience with large character rosters while making individual storytelling an explicit feature from the beginning.
The official website also presents several organizations and factions operating across the city, ensuring that the cast extends well beyond the central Dynamite Blue agency.
Six Elements and Guardian Stone Breaks Shape Combat
Dynamite Blue uses a turn-based battle system built around six elements with interconnected strengths and weaknesses.
Correctly targeting an enemy weakness can trigger a Guardian Stone Break, a mechanic intended to shift the momentum of a fight when players exploit the elemental relationship effectively.
The party also shares a resource called BP.
Rather than belonging to a single hero, BP is generated and spent across the team, making resource management part of party construction and action order.
Store descriptions emphasize that different character combinations can produce different battle approaches, giving the roster a strategic function beyond collection.
Nine Languages Include Indonesian at Global Launch
Kosmo's12 confirms that the worldwide build supports nine languages: Korean, English, Japanese, Simplified Chinese, Traditional Chinese, French, German, Indonesian and Thai.
Indonesian support is particularly notable because older versions of the Steam storefront previously showed only five languages.
The newest global announcement now places Indonesian alongside four additional languages for launch.
The developer also says reports and improvement suggestions submitted through its official Discord are being incorporated into live updates.
Because Korea has already been operating since July, the September 30 version is not starting from an entirely untouched build; it is described as reflecting earlier live-service experience and feedback.
Kosmo's12 Reunites Core Exos Heroes Developers
Kosmo's12 is a new Seoul-based studio established in February 2026.
The company describes itself as reuniting the director, art director and several core developers who previously worked on Exos Heroes.
Youngzun Choi serves as CEO and Director, while Minsuk Son is the Art Director.
Dynamite Blue is the studio's first project, emphasizing collection-RPG design, pixel-art combat, AFK progression and a cyberpunk setting intentionally written with a less melodramatic tone.
Steam also contains a dedicated AI-generated-content disclosure. The developer states that some character art and backgrounds use AI-generated images as a starting point before being extensively edited by the art team to fit the game's final visual style.
Why This Matters
1) The Exos Heroes team is returning with a new IP
Dynamite Blue is not a sequel, but it brings together developers already experienced with large character-driven RPGs.
2) Indonesian support arrives on day one
Indonesian is part of the nine-language global lineup rather than a localization promised for a distant later update.
3) Character collection is tied directly to storytelling
More than 60 heroes come with Pocket Stories, connecting the collection system with the world-building of Vierhaven.
4) Korea serves as an early operational phase
The ONE store release has given the team a real live-service period to collect feedback before the worldwide launch.
